Laser Therapy and Dementia: A Database Analysis and Future Aspects on LED-Based Systems

Figure 4

Transmission factor of different types of laser (modified from [20]) and of the new medlouxx system (LED). The results from violet (405 nm), green (532 nm), yellow (589 nm), red (658 nm), and infrared (810 nm) lasers are based on a previous study [20]. The system based on LED showed the highest mean value of the transmission factor (830 nm infrared light). The lines in the boxes represent the median, the ends of the boxes define the 25th and 75th percentile, and the error bars define the 10th and 90th percentile.
